NAME

   VolPack - introduction to VolPack, a library for volume rendering

SYNOPSIS

   #include <volpack.h>

   cc file.c -lvolpack -lm

DESCRIPTION

   VolPack  is  a  portable  software library for volume rendering.  It is
   based on a new family of fast volume rendering algorithms (see Philippe
   Lacroute  and  Marc  Levoy,  Fast  Volume  Rendering Using a Shear-Warp
   Factorization of the Viewing  Transformation,  Proc. SIGGRAPH  '94,  in
   Computer Graphics, Annual Conference Series, 1994, pp. 451-458).  For a
   tutorial introduction to the library see the VolPack User's Guide.

DATA TYPES

   The  following  data  types  are  declared  in  the VolPack header file
   (volpack.h):

   vpContext
          An opaque handle for a rendering context.   A  context  contains
          all  of  the  information required to render a volume, including
          classification and shading parameters, the view  transformation,
          a description of the format of the volume data, and private data
          structures used by the rendering routines.

   vpResult
          A result code.  Most of the library  routines  return  the  code
          VP_OK  upon  successful  completion,  or  an  error  code if the
          library call fails.

   vpVector3
          A  three-element  linear  array  of  double-precision   elements
          (double[3]).

   vpVector4
          A   four-element  linear  array  of  double-precisions  elements
          (double[4]).

   vpMatrix3
          A   three-by-three   array    of    double-precision    elements
          (double[3][3]).

   vpMatrix4
          A    four-by-four    array    of    double-precision    elements
          (double[4][4]).
